My invention relates to racks for supporting display sheets such as, and more particularly, maps wound upon spring rollers and commonly used in educational institutions. 1

One of my objects is to 'provide a rack of simple,- relatively inexpensive, and durable construction for removably supporting. there. in a plurality of frames on which the rollers and the individualdisplay-sheet-supporting frames may be removed therefrom and used atany desirable location',-'such an arrange ment being especially advantageous to com munities where the cost of providing each room with the same set of display sheets would be prohibitive.

Another object is to provide a novel, simple, inexpensive, and' durable construction,

of frame in which the display sheet supporting roller is journalledf and other objects as will be manifest from the following descriptionivn" Referring to the accompanying drawing: Figure 1 is a view in front elevation of a rack constructed in accordance with my irrrvention and shown as housing one of'a plurality] of display sheet-supporting frames adapted to be housed within the rack. I Figure 2 is a plan view of one of the similar frames referred to. r

broken sectional Referring to the'rackconstruction shown, 1t comprises a frame 7' shown as formed of an upper member 8, a lower member 9 and end members 10 and 11. :These members, which preferably are formed of wood, may beseeure'd together in any desirable way as for example bysetting the upper and'lower ends of the members 10 and 11 into gains 12 and'13 in the members 8 and 9, respectively, these parts being held together by screws (not shown) or any other "suitable fastening "devices,e2itending through the members 8 and 9 andinto the members 1 0 and 11.1

The frame Tat its opposite ends is provided with-vertical'series of ledges 14 and 15 respectively, adapted for the supporting of a vertical series of horizontally extending display-sheet-supporting' frames of the same construction; one thereof being represented at 16'; and hereinafter'described;

Tlie'ledges 14 are shown'as formed of tongues cut from the metal of a strip 17 of angular shape in-cross section presentinga plate 1 portion 18 extending substantially parallel with*the front face of the rack; a forwardly p rojecting flange'ltl at which the member 17 fits flatwise against the inner Surface of the cross member 11 and to which it is. l

secured, as for example by the screws represented at '20,f and a rearwardly extending flange 21 at its oppositeedge from the metal 'of'which the ledge-forming tongues 1 1 are cut, these tongues being bent toextend into substantially liorizontalposition as shown.

The distancebetween', adj acent ones of the ledges-14 is considerably greater than the height of the frames 16 and to prevent shift-i ing ofthe racks inthe planeofthe members 17, other tongues represented at 22' are cut from the flange 21 of themember 17 .the

frames 16 fitting fairly snugly in between the ledges 14 and the adjacent ones of the of levers 23 pivotally mounted, as indicat-cd at 24 on .the plateportion 18 ofthe member 17 The ledges 15 in the particular construction shown are formedof tongues bent. rearwardly from the metal of a flange portion 25 ofa plate member 26 which fits 'flatwise against the inner surface of'the cross memfiber 10 and is secured thereto, as forrexample by the screws represented at 27, other tongues 28 being formed from the metal ofthe flange 25 and corresponding ith, and functioning in the same way as, the tongues 22. V Thexledges 15 thus provided are set back inwardly ofthe free edge ofthe flange'25 7 whereby portionsof the latter and represented-at 29 extend in such a position that when the fraines16jare positioned in'the. rack, theseportions 29.will form abutments preventing forward displacement of the frames 6 16 at their left-hand ends in Fig. 1.

It may be" here stated that the rack 7 t the rear ofthe portions 29 and in spaced rela t1on thereto is provided with a rear abutment 30 which maybe in the form of a wooden board preferably secured to the inner'side of the crossmember 10 and of substantially the same height as the member 2526 the frames '16 at their left-hand ends fitting between the plate portions 29 and the abutment 30. The

opposite end of the rack 7 is provided with a similar abutment'represented at 31 for. the right-hand ends of the frames 16 which latter, when positioned in the rack and the levers 23 are swungzto'a position for lapping the 7 frames 16,extend between these levers and the abutment 31 as shown in Fig. 6.

Referring now to the. particular illustrated construction of. frames 16, it comprises a rear bar 32 shown as .formedof sheetmetal bent into the cross sectional shape represented in Fig. 3 whereby this member is in the form of a hollow bar open at its rear side throughout its length as representedv at 33. 'The frame also comprises end pieces 34 shown as in the form of metal plates 35 the metaliat the edges I of these plates being bent'ov'er to form flanges 36,37, 38 and 39, the members 34 being secured to the front faces of the members 32 by screw bolts 40 extending through the flanges 37 andthe frontjwall portions of the members 32. The flange 39 is formedwith an extension 41 at its upper end which-curvesupwardly and, outwardly beyond the 'platef35, these two flangeextensions 41- at the opposite ends' ofthe frame'16 forming stops in position to be engaged by the ends of the binding-bar,

The member 17 is also provided with means or stiffening strip, represented at 42 and com monly provided along thelower edge of the roller mounted display sheet represented at 43, the ends of the member 42 extending beyond the lateral edges of the sheet 43 and in a position to engage the stop flanges 41 under the'action of the spring roller represented at 44 on which the display sheet 43 is wound.

The spring roller 44 may be of any suitable construction, as for example that commonly used in constructions of this kind, one end thereof having a j ournaling portion 45, as for example the left-hand end in Fig. 1 which is journalled in the plateportion 35 of the adjacent'endmember 34'of the frame 16 and the other end having a portion 45 of. angular shape. inv cross section which is connected with the spring of the roller and extends into an opening 46of similar shape in the plate 35 of the adjacent end member34, whereby upon pulling down on the bar member42the display sheet 43 'unwinds from, the roller into display position against the resiliency of the spring deviceof the roller. I I

The frame member .32 projects at its ends beyond the cross members 34, and in positioning the frame 16 in the rack, the left-hand end" of the member 32 (Figs. 1 and 2) is inserted into the space between one of the ledges 15 and a tongue 28 immediately above the latter and between the portion 29 and the rear abutment 30. The frame is then swung at its right-hand end to become positioned between one of the tongues 14 and the tongue 22 immediately above the latter and the one of the levers 23 positioned adjacent thereto thenswung to the position shownin Fig. 4 whereuponthe frame 16 becomes confinedbetween the .rear stop member 31 and the lever 23 referred to, it being noted that the member 18is'provided with a series of projections 47, one-for cooperation with each lever 23 tolimitcounter-clockwise rotation of these levers I beyond the position shownof the one in Fig. 4 in lapping engagement with the frame 16.

It will be understood from the foregoing that the rack thus provided is adapt-edjto receive a plurality of the frames 16 (the particular construction.v shown being adapted to receive four of these frames) which become disposed therein in substantially parallel horizontal position and in a series extending vertically. In the arrangement shown any one of the display sheets 43 may be unrolled for display purposes, without disturbing any of the other sheet-supporting devices in the rack, and when it is desired to use any one of the individual sheet-displaying devices at another location than at the rack,as' for example in another room of a building in which the rack is provided, such device ;may be readily removed from the rack and hung at the desired location, as for example upon hooks (not shown) projecting from a wall and adapted to be received into slots 48 provided in theupper surface of the bar 32 adjacent its opposite ends.

While I have illustrated and described a particular construction embodying my invention, I do not wish to be understood as intending to limit it thereto as the same may be variously modified and altered without departing from the spirit of my invention.

What I claim as new, and desire to secure by Letters Patent, is:

1. A roller-mounted display-sheet device comprising a frame formed of a rear bar member of sheet metal having its long edges bent rearwardly in opposite directions to form a bar of hollow form in cross section, brackets having end plate portions and upper, lower and rearflanges located at the ends of said hollow bar, said rear flanges flatwise opposing the front portion of said bar and being secured thereto, aroller journalled on said plate portions, and a display sheet wound on said roller.

2. A rack comprislng a frame havmg supports for a plurality of removable and re- I placeable roller-mounted-display-sheet supporting frames, stop means preventing rear ward displacement of said second-named frames, and pivotally mounted devices on said first-referred-to frame and extending beyond the end facesof said second-named frames and adapted to be rotated into lapping relation to said second-named frames of, and spaced from, said stop means and between which said second-named frames, at

one end, extend, and stop devices at the end of said first-referred-to frames for holding said second-named frames against forward displacement, pivoted to said first-referred-to frame beyond the adjacent ends of said.

second-named frames and adapted to be rotated into positions in which they lap thefront sides of said second-named frames.
